Background: Previous studies assessing the hypothesis that the construct of 'aberrant salience' is associated with psychosis and psychotic symptoms showed conflicting results. For this reason, the association between measures to index aberrant salience and subclinical psychotic symptoms in a general population sample was analysed. In addition, genetic vulnerability was added to the analysis as a modifier to test the hypothesis that modification by genetic vulnerability may explain variability in the results.

Prior research suggests that secure base script knowledge is categorically distributed in middle childhood but becomes dimensionally distributed from late adolescence onward, potentially indicating a developmental shift in the nature of secure base script knowledge. Secure base script knowledge may initially be sparse, giving rise to categorical individual differences, while increased relational experiences later in development might contribute to more elaborated secure base script knowledge and dimensional individual differences. However, the cross-sectional nature of prior research limits inferences about developmental changes.

Patients with differences of sex development (DSDs) have complex anatomy and surgical needs related to both Mullerian and non-Mullerian structures. Approaches to vaginal reconstruction for these conditions are guided by individual anatomy, with the goal of establishing unobstructed outflow for the reproductive, urinary, and gastrointestinal tracts. Patients may have anatomy requiring vaginoplasty for either outflow tract obstruction or chosen sexual function.

Article Synopsis
  • This study assesses how well a commercial AI system can identify normal chest X-rays and its ability to help reduce the workload for radiologists.
  • Researchers analyzed over 1,600 radiographs, categorizing them and evaluating the AI's performance, which showed a high accuracy with a score of 0.92 for detecting normal results.
  • The findings suggest that the AI could potentially eliminate the need for radiologist reporting on about 50% of normal X-rays, which could reduce their workload significantly.

We present a novel method to measure the arrival time statistics of continuous electron beams with subpicosecond resolution, based on the combination of an rf deflection cavity and fast single electron imaging. We observe Poissonian statistics within time bins from 100 to 2 ns and increasingly pronounced sub-Poissonian statistics as the time bin decreases from 2 ps to 340 fs. This 2D streak camera, in principle, enables femtosecond-level arrival time measurements, paving the way to observing Pauli blocking effects in electron beams and thus serving as an essential diagnostic tool toward degenerate electron beam sources for free-electron quantum optics.

Sitosterolemia is a rare autosomal recessive genetic disorder in which patients develop hypercholesterolemia and may exhibit abnormal hematologic and/or liver test results. In this disease, dysfunction of either ABCG5 or ABCG8 results in the intestinal hyperabsorption of all sterols, including cholesterol and, more specifically, plant sterols or xenosterols, as well as in the impaired ability to excrete xenosterols into the bile. It remains unknown how and why some patients develop hematologic abnormalities.
